1. A three-dimensional (3D) coordinate measurement system, comprising:

  • a retroreflector;

    a laser tracker including;

    a first light source configured to emit a first beam of light from the laser tracker;

    a structure rotatable about a first axis and a second axis;

    a second light source;

    a first camera proximate the second light source; and

    a processor responsive to executable instructions which when executed by the processor is operable to;

    in a first instance, determine that a follow-operator gesture has been given by an operator and in response rotate the structure to follow movement of the operator; and

    in a second instance, determine that a lock-on gesture has been given by the operator and in response, steer the first beam of light onto the retroreflector.
